Notes on Phoradendron flavescens, Nutt. II. 
BY J. SCHNECK. 
The northern limit of this species, so far as I can ascertain, is 
near 40° N. lat., except near the Atlantic and Pacific coasts. 
Gray’ and Wood? both give its habitat as New Jersey to Illinois. 
and southward. Wm. M. Canby? reports it as ‘‘ frequent” on the 
peninsula between Delaware and Chesapeake Bay. Lester F. 
Ward' reports it from the vicinity of Washington, D. C.; John 
M. Coulter and C. R. Barnes? for the State of Indiana, as “com- 
mon south.” H.N. Patterson® reports it from Wabash and Jack- 
son counties, in Illinois. The most northern station given in the 
Pacific R. R. Rep., is Benicia, California. It is not mentioned in 
Bot. King’s Exped. ; while in Bot. Wheeler’s Surv. W. of 100th 
meridian var. villoswm is reported from Oregon. . 
Canby writes me that he has observed it between Trenton and 
ew Brunswick, N. J. These last two are the only stations of 
which T have any knowledge north of 40° N. lat. Mt. Carmel, IIl., 
1s near 38° 30’ N. lat., with a range of temperature from +104° 
to —26° Fahr. When we have several consecutive mild winters 
the mistletoe becomes common, but is again almost exterminated 
by the return of continuous cold westher, in which the thermome- 
ter remains at or below zero for a number of consecutive days. 
The winters of 1878-79 and 1880-81 were remarkable for the 
great number of continuous cold days, and came near extermina.

comparatively mild, and as a result the mistletoe was quite abund-

passed through has killed most of the bunches. 
Does the mistletoe injure the host upon which it grows? My
